I get a few more percent from overscan calibration. Add a bit more for careful tweaking of rejection and scaling algorithms and now you're talking about an easily visible improvement.
Darks may be optional with the new Sony sensors. Mike S certainly seems to think so...

Speaking of that, what rejection parameters have you found workable? I tend to only use hot and cold pixel rejection and have noticed that helps. I have not noticed the other rejections to help at all unless I am simply using the wrong settings.
